Hey, Im no expert, but I think if you were to print out the public key (bitcoin address) on one side then print the private key for the address on the other side in such a way as to be able to hide the private key if you fold the paper in half, then seal it with tape or something so that only the public key were visible until the seal were tampered with, I think that would work.
::edit::
oh, also send some coins to the address. this is basically a cold storage paper wallet.
